Different Types of Screen Cables

Braided screen cable:

This type of cable has a braided metal screen that surrounds the conductors. The braid is typically made of multiple wires that are woven together to form a tight mesh.

Foil Screen cable: 

This type of cable has a thin layer of metal foil wrapped around the conductors. The foil is typically made of aluminum, and is bonded to the insulation to provide a continuous shield.

Combination Screen cable:

This type of cable combines both braided and foil screens for maximum EMI protection.

Screen Cable

When selecting a screen cable, it is important to consider the specific requirements of the application, including the level of EMI protection needed and the operating environment. It is also important to properly terminate and ground the cable to ensure effective EMI protection.

Shielding offers the benefits of significantly improved pair-to-pair crosstalk performance, alien crosstalk performance, and noise immunity that cannot be matched by any other cabling design strategy. (Application- Analog Signal handling

What is the full form of XLPE Cable

XLPE means for cross-linked polyethylene. This and other cross-linked synthetic materials, of which EPR (ethylene propylene rubber) is a notable example, are being increasingly used as cable insulants for a wide range of voltages.

Polyethylene has good electrical properties and in particular a low dielectric loss factor, which gives it potential for use at much higher voltages than PVC. Polyethylene has been and still is used as a cable insulant, but, as a thermoplastic material, its applications are limited by thermal constraints.

XLPE cable is suitable for voltage ranges from

XLPE (cross-linked polyethylene) cable is suitable for voltage ranges from low voltage (LV) up to extra high voltage (EHV) levels. The specific voltage range depends on the design, construction, and specifications of the XLPE cable, 

But it can typically range from 300 volts up to 500 kV or higher. XLPE cables are widely used for power transmission and distribution, as well as in industrial and commercial applications, due to their excellent electrical and mechanical properties, high durability, and resistance to environmental factors.

DC Power Cables

DC power cables are electrical cables designed for transmitting direct current (DC) power from a power source to an electrical device or load. DC power cables are commonly used in a variety of applications such as in automobiles, solar panels, computer power supplies, and telecommunications equipment.

DC power cables are available in various sizes, lengths, and materials, depending on the application requirements. The most common materials used for DC power cables include copper, aluminum, and silver-plated copper. Copper is the most widely used material due to its excellent electrical conductivity, durability, and low resistance to current flow.

When selecting a DC power cable, it is important to consider the voltage and current ratings, as well as the environmental conditions of the application. High voltage and high current applications may require thicker cables with a larger gauge size, while harsh environments may require cables with special jackets or insulation to protect against moisture, chemicals, or extreme temperatures.

It is also important to ensure that the connectors used with the DC power cables are compatible with the cable size and type, as well as the equipment they will be connected to. Proper installation and maintenance of DC power cables can help to ensure safe and reliable operation of electrical systems
